I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Plenty of open space to fly but no parking other than at the roadside. North Down Model Aircraft club site is across the road from the track (flying for members only).
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 08/09/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
